| Zusammenfassung |
| Rainfall erosivity refers to the ability of precipitation to erode soil, and
depends on characteristics such as its total volume, duration, and intensity and
amount of energy released by raindrops. Despite the relevance of rainfall
erosivity for soil degradation prevention, very few studies have addressed its
spatial and temporal variability. In this study the time variation of
rainfall erosivity in the Ebro Valley (NE Spain) is assessed for the period
1955–2006. The results show a general decrease in annual and seasonal
rainfall erosivity, which is explained by a decrease of very intense rainfall
events whilst the frequency of moderate and low events increased. This trend
is related to prevailing positive conditions of the main atmospheric
teleconnection indices affecting the West Mediterranean, i.e. the North
Atlantic Oscillation (NAO), the Mediterranean Oscillation (MO) and the
Western Mediterranean Oscillation (WeMO). |
